SeekAlignedToLastTick aligns the seeked time of the Storyboard with the last clock tick. Values are immediately updated to reflect the changes due to SeekAlignedToLastTick, even though the screen will not reflect these changes until the screen updates.

Note that seek operations do not take the storyboard's SpeedRatio or SlipBehavior settings into account: the storyboard is treated as though it had a SpeedRatio of 1 and no SlipBehavior.
